Dialing in doser questions

[b4tn]

I am getting my doser dialed in for a mixed reef. 3 weeks of tweaking I am now currently, with 10 gallon every two week water change, getting a consistent Calcium of 500, Alkalinity of 9, and magnesium at 1360. Does this look good or should I bring the calcium down a bit and the alk up to 10?

Bring calcium down and leave alk at 9. Lower mag to 1300
